Explanation: The oxygen atom of the water molecule thus has a steric number of 4; as does carbon in methane; as does chlorine in perchlorate, ClO− 4. Answer link WebCount the number of lone pairs + the number of atoms that are directly attached to the central atom. This is the steric number (SN) of the central atom. SN = 4 → sp³. SN = 3 → sp². SN = 2 → sp. For example, the O atom in water (H₂O) has 2 lone pairs and 2 directly attached atoms. ∴ SN = 2 + 2 = 4, and hybridization is sp³. lsw lackierservice
